BEAM-SPACER.

To all whom it may concern:

Be it known that I, WILLIAM E. WHITE, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Beam- Spacers, of which the following is a specification.

My invention relates to concrete reinforcing devices and particularly to a novel spacer adapted for. use as a means for retalning the bars employed for reinforcing concrete beams.

One of the principal objects of the invention is to provide an extremely simple device adapted to be built up from easily procured sections of metal, such as drawn wire, the parts being held in proper relation preferably by electric welding. In the device here disclosed I have provided for the utmost simplicity only such elements being employed as are capable of performing a double function. To that end the legs or spacing elements, employed for efiecting the elevation of the reinforcing bars above the form, are so constructed as to perform not only the function described but that of suitably spacing the bars laterally. Furthermore, the side members which have the function of rigidly uniting the legs have also the function of supporting the reinforcing bars in their elevated position.

A device constructed as described, and as shown in the drawing, combines the features of strength and lightness in weight to an unusual degree and in addition is adapted for the spacing of multiple rows of reinforcing elements with slight modification.

The invention will be more readily understood by reference to the accompanying drawing wherein:

Figure 1 is a perspective view showing a pair of beam spacers and their relation to a reinforcing bar, the lower being termed the primary spacer and the upper the secondary spacer;

Fig. 2 is a fragmentary side view of the primary spacer;

Fig. 3 is an end view thereof;

Fig. 4 is a fragmentary side view of the secondary spacer; and

Fig. 5 is an end view thereof.

In the drawings I have not illustrated the forms by means of which the beam is outlined as the use of beam spacing devices is well known. Both the primary and secondary spacing devices comprise identical e1e- Specification of Letters Patent.

ing oppositely downwardly and outwardly from a horizontal line which is coincident with the longitudinal axis of the connecting member 11. A plurality of pairs of so formed legs are joined by means of side members 12, 12, which are welded to the legs at a point midway of the height of the legs. Thus there is formed between each pair of legs a recess or pocket 13 adapted to receive and support a reinforcing bar 14, as shown in Fig. 1, and as indicated in dotted lines in Fig. 2. Because of the depth of the pocket the bar is held in position without the use of additional fastening devices.

The secondary spacing member, best shown in Fig. 4, is identically constructed and comprises legs 15, adjacent oppositely extending legs being connected by a horizontal member 16 and the pairs of legs being joined by side members 17 welded in position. In addition I provide side members 18 which are welded to the legs at the lower extremities thereof and these serve as a means of support for the secondary spacer on a row of reinforcing bars held by the primary spacer, as shown in Fig. 1, and as indicated in dotted lines in Fig. 4. The vertical space separating rows of reinforcing bars is determined by the distance between the side members 17, 18 and this distance can be varied as desired in making up the secondary spacers. In Fig. 4 I have indicated the lower reinforcing bar at 14 and the upper bar at 19.

I have found it most economical to employ heavy wire as the material for forming these spacers particularly for the reason that there is no waste whatever in construction, the material may be readily procured and, when properly designed, provides the greatest strength per unit of metal. It will be understood, however, that the form of the material is not essential and modifications may be made not only in the cross-section of the metal but in the arrangement of the parts all without departure from the spirit of my invention.

I claim:

1. A beam spacer comprising in combination a pluralit of spacing elements, each element consisting of a length of wire bent tially as described.

horizontal members in line with each other,

and a horizontal side member at each side of said spacing elements, said side members being welded to adjacent legs of said spacing elements at a point intermediate the ends of the lggs.

2. spacing device including legs, adjacent legs projecting diagonally oppositely from a horizontal llne, adjacent legs being joined'by a connecting member the longitudinal axis of which is coincident with said line, and side members secured to the legs to hold the same in rigid relation, substan- 3. A spacing device including legs, adjacentlegs projecting diagonally oppositely from a horizontal line, adjacentlegs being joined by a connecting member the longitudinal axis ,of which is coincident with said line thereby forming pairs of legs, and side bars secured to the legs at a point below the upper ends thereof, the space between adjacent pairs of legs forming a pocket for the reception of a reinforcing bar, substantially as described.

4:. A spacing device composed of a plurality of pairs of legs, the legs of each pair eenoes projecting downwardly and oppositely outwardly from the ends of a horizontal connecting member, and horizontal side bars welded to the legs and arranged in parallelism with said connecting members, substantially as described.

5, A spacing device composed of a plurality of pairs of legs, the legs of each pair projecting downwardly and oppositely outwardly from the ends of a horizontal connecting member, and horizontal side bars welded to the legs and arranged in parallelism with said connecting members, the side,

bars being located at a point below the upper ends of the legs thereby forming a pocket between adjacent pairs of legs for the reception of a reinforcing bar, substantially as described.

6. A spacing device composed of a plurality of airs of legs, the legs of each pair projecting downwardly and ppositely outwardly from the ends of a orizontal connectin member, horizontal side bars welded to the egs and arranged in parallelism with said connecting members, and additipnal side bars secured to the legs at their lower extremities, substantially asdescribed.
